Single Use Bioprocessing Components lower production costs, decrease time to market and reduce the risk of cross contamination. Our patented flow path components include polypropylene barbed flanges with a platinum cured, medical grade silicone gasket mechanically attached to the fitting face. Bioclamps™ are a patented tri-clamp with a quick release, providing an easy assembly and secure connection between our barbed flanges and polypropylene BioEnd Caps™ BioEnd Caps are designed to permanently terminate a disposable manifold until an in-process new sterile connection is made. To control the fluid flow rate, use Biovalves™ which can be easily added to preassembled systems without cutting tubing lines. All Qosina bioprocessing components are made from Class VI compliant materials.

Needleless or luer-activated valves are normally closed but open with the male luer tip of a syringe, or other male luer connector. Available in single, T, Y and multi-port manifold styles, Qosina stocks a selection in various materials, sizes, and designs including swabbable valves.

Qosina offers a large selection of hemostasis valves and tuohy borst adapters which provide a seal for secure positioning and prevent backflow. Hemostasis valves also feature a side port with a female luer lock for easy attachment of a secondary line. Many sizes are available; up to 10 French for our hemostasis valves and up to 18 French for our tuohy borst adapters.
